Launch crp909 scanner is a great deal at this price! I use it as a secondary scan tool. So far impressive. I use it both at home and work. I upgraded from the Crp229. This tool is fast to boot up and retrieve codes and info. Love the larger touch screen. It’s a simple tool, very straightforward, without all the stuff you don’t really need!

I like the crp909 scan tool, it works well for my 2015 BMW, it automatically scans the VIN and learns the model of your car, you don’t even need to choose any car model, it scans all systems fault codes and determine what is required to fix cars.

What it can’t to do is immo key programming. I wanted to add a key fob to one of my cars and it was not able to do that either.
